Chapter 4.4, Problem 16PPS

To determine

To calculate:To solve the equation and check the solution

Answer to Problem 16PPS

Solution is $x=-15$

Explanation of Solution

Given information:Equation is $0.3x=-4.5$

Calculation:

Given equation is as follows:

  $0.3x=-4.5$

On solving the equation,

  $\begin{array}{l}x=\frac{-4.5}{0.3}\\ x=-15\end{array}$

Now, in order to check the solution, substitute $x=-15$ in equation $0.3x=-4.5$

  $\begin{array}{l}LHS:0.3\left(-15\right)\\ LHS:-4.5\end{array}$

Since, $LHS=RHS$

Thus, $x=-15$ is solution of equation $0.3x=-4.5$

Hence,solution is $x=-15$
